To all whom it may concern,.- inbefore named, preparatory to again repeat.- Be it known that I, HORACE WYMAN,a citiing the operation described, the insertion of zen of the United States, and a resident of the third pick completing the cycle of oper- Worcester, in the county of Worcester and ations, each cycle including three complete 5 5 State of Massachusetts, haveinvented an Immovements of the needle while the lay is at provement in Looms for- Weaving Tufted rest and three complete .movements of the Fabrics, of which the followingdescription,in lay while the needle is at rest, there being a connection with the accompanying dra'wings, shed for each needle action, the fabric made is a specification, like letters on the drawings, being that represented in United States Pat- 6o o representing like parts. ent No. 245,259, dated August 2, 1881, with Thisinvention relates toloomsfor weaving l the exception that in said patent each pick tufted fabrics, and relates more especially to of weft is represented as composed of four the so-called needle and lay motionsthey threads,whereasin the presentinstauce each being organized and operated in a novel manpick is com posed of but two threads, the pick 65 ner and time to enable the production of a being a double pick. larger amount of fabric in agiven time, the I have found by experiment that I may run machine being run at a certain speed; and the the loom herein to be described and produce invention also comprehends improvements a greater amount of fabric of standard qualin the mechanism for operating the spoolity than can be produced on looms as now or- 7o zo frames and also in the frames themselves. In ganized for this work, and I have effected looms of this class the weft is customarily inthis larger production of work by increasing serted in the open shed from one side thereof the speed of the loom and by inserting the by a needle, and the weft, laid in the shedl first pick of the cycle of weaving movements double or in the form of a loop, is entered at and the tufts-holding pick each in rapid suc- 75 25 the side opposite that at whichit was inserted cession in its own shed while the lay is held by a selvage-thread which may be carried by cin its inoperative position, the lay being a shuttle, and the needle is then retracted moved after the insertion of two double picks from the shed and held stationary, while the to beat said two picks at one operation, one lay comes forward and beats the weft up to pick holding the tufts into their proper posi- 8o 3o the fell, and thelay is retracted, asecond shed tion in the woven fabric and the third or last is opened in the warp in frontof the reed, the

pickof the cycle being inserted and beat in in tuft-yarns, held in suitable guides of a spoolusual manner. To enable this increased proframe, are preferably presented in the shed duction of fabric, I have devised means for then open, so that the free ends of said yarns actuating the weft-inserting needle in rapid 85 35 are left above the warp, and the weft-consuccession to tberebylay the weft in two sheds trolling needle is then operated to lay a weft formed in rapid succession by usual harness in said shed, it preferably crossing or holding mechanism or frames, one shed immediately the tnft yarns in the usual manner, and the after the other, the lay remaining at rest and needle is retracted and held stationary while away from the fell while the first two picks of 9o 4o the lay is moved forward a second time to the cycle of weaving are being inserted, the beat in the second weft, this second pick of lay acting rstin each cycle only after the secweft beat ,into the fell taking with it the tuftond or tuft-yarn-holding pick is made, it beatyarns, which are cut off in usual manner, ing in said second and the previous laid pick. leaving tufts in the fabric, after which the I have also devised new means for imparting 95 45 lay is again retracted and another or third a variable movement to the lay, it being acshed is formed in which the needle again lays tuated in a novel time and order with relaa third weft and retires, andthe lay is again tionto the needle mechanism, or, in other moved for the third time to beatin the third words, l utilize one beat of the lay to beat weftcrossing and bind the tufts into the up two picks of weft inserted in succession in 10o 5o; fabric, the lay then retiring and ashed being two sheds made one following the other rapopened corresponding with the first shed,here idly. I have also provided means whereby the harness mechanism employed to form sheds is actuated rapidly to form two sheds,

one immediately after the other while the lay is at rest, said sheds being formed one following the other with a shorter interval of time than the time between the second and third sheds, the latter requiring a much longer time, because of the fact that the lay is then actuated to beat in and second picks preparatory third shed. The lay occupies position and remains there while the needle controlling the weft inserts two successive to making a picks of double weft in the two sheds, the lay then being moved to beat into the fell said two picks and when the lay retires again and remains in its backward position while auother pick is inserted in a third shed, when it is immediately again moved forward to beat in that pick to the fell, it again retiring and remaining in its backward position while two other picks are inserted.

I have described the cycle of movements as being repeated with each three picks, that number of picks binding in a row of tuftyarns; but the cycle may include a greater number of picks in securing the tnft-yarns in the fabric, so long as there shall be at times apick inserted in two sheds iliade one after the other in rapid succession without an action of the lay, or, in other words, so long as the lay is held at rest at times and made to beatinto the fell two successive picks, each in its own shed, rather than beating each pick immediately7 after it has been laid into its own shed. So, also, in this class of looms the tuft-yarn is wound on a series of spools mounted in spool-frames detachably connected with an endless chain, and when a row of tufts is to be put into the fabric one of these frames is taken from the chain by transferring mechanism, which presents the tubes containing the tuft-yarns into the Warp, said yarns being interwoven therewith and thereafter severed between the warp and the spool-frameto form tufts, the spool-frame being then returned to the chain by the upward movement of the transferrer, it leaving the frame in the chain and immediately thereafter the relative positions of the transferrer and spool-frame is changed, so that the transferrer in its next operative movement will engage and detach from the chain the next spoolframe of the chain following the one last removed. The chain remains stationary whilethe spool-frame is detached to supply tuft-yarns to the warp and is returned'into its position in the chain, the chains being advanced step by step commonly for the distance of one spool-frame from the next frame p in the chain that a fresh spool may be taken by the transferrer at each operation.

In practice with carrying-chains containing a large number of spools it has been found that when the chains are advanced by moving the shaft employed to actuate the chain, such movement being effected by a pawl-andat one operation the first its backward ratchet motion, the resistance offered by the chain in moving is so great that sometimes the shaft fails to be turned for just the proper distance to put in its proper operative position the frame next to be taken from the chain by the transferrer, and consequently the frames fail to register properly with the transferrer, and the transferrer is therefore rendered inoperative and fails to takea frame from the chain. To overcome this ditliculty, I have provided main and secondary chainactuating means, each being moved intermittingly at suitable times by devices acting substantially in unison for the whole or a portion of the time to thus move the chain intermittingly step by step. The secondary chaindriving means cooperates with and starts what Ishall designate the registering-shaft, it directly engaging that part of the chain from which the spool-frames are taken and returned, said registering-shaft insuring the accurate positioning ofthe spool-frames to be taken by the transferring means. actuating means for the chains move the same intermittingly from a position of rest, and, as herein shown, the chains are engaged positively both in the upperand lower run thereof, said main actuating means doing the chief amount of work in overcoming the weight of the chain in moving it step by step, the secondary means aiding in starting the chain in motion and insuring that that particular part of the chain from which is to be taken the spool-frame to be used shall be accurately and unerringly moved to insure the proper position for a spool-frame to be taken from and returned to the chain.

'lhe chain when applied in theloom is provided in both runs to the right of the main actuating means for the chain with a defined amount of slack, and the registering-shaft acts in the turn of the chain or lhe part of the chain from which the spool-frames are taken, and owing to this slack chain thc registering-shaft may easily start the chain, the main actuating means acting thereafter to lmove the bulk of the weight of the chain.

The main and secondary chai n-moving means may be driven at the same speed or one may be driven at a relatively dilferent speed, so that one will start before the other. The main and secondary chain-moving means are both driven intermittingly from a suitable continuously-moving shaft.

I employ an auxiliary chain as a secondary chain-moving means, it turning the registering-shaft.

It is desirable at times to move the carrierchain while the loom is at rest, and here'tofore this has been done by the operator through a lever which, moved by hand, actuated the chain step bystep; but when a large number of spool-frames are employed, as in long patterns, and especially in looms for weaving wide fabrics, the movement of the chain by hand requires very considerable 1abor on the part of the operator.

So I have The main i devised means whereby when it is desired to move the chains other than in their regular operation I may disconnect a shaft, herein employed as the driving means for the chains during the regular operation of the loom in weaving, and throw into operation an independent auxiliary driving mechanism. I have also devised a new spool-frame, my aim being to provide a spool-frame having great strength and presenting the minimum of weight, said frame sustaining a plurality of spools end to end.

Referring to the drawings, Figure 1 represents a partial front elevation of the righthand side of a loom embodying my present improvement, the figure showing only the mechanism for actuating the needle, part of the figure being broken out to save space upon the drawings. Fig. 2 is a right-hand broken end view of only the needle-actuating mechanism represented in Fig. 1, the chains, the transferring means, the lay, and their actuating mechanisms being omitted to avoid confusion in the drawings. Fig. 3 represents a partial right-hand side elevation, parts being in section, it showing chiefly the auxiliary chain for starting the spool-frame shaft, the transferring mechanism, and the lay, other parts of the loom ushown in Figs. 1 and 2 being omitted.

The framework A, the shaft B2, the arm 614, connected to the rock-shaft @13, the extended arms @12,c0nneeted .with the link e1,attached to and imparting backward-and-forward movement to the guide-lever e8, the slide e3, fitted in said guide-lever and having jointed to it by a link f2, carried by the end of a lever 125, adjust-ably connected by link f3 to said slide and connected with a shaft having an extended arm f1, provided witha suitable roller or other stud, are substantially the same as in United States Patent No. 446,402, dated February 10, 1891, and No. 490,237, dated January 17, 1893, and said devices constitute one form of usual transferring mechanism to engage the spool-f rames, take them from carrying-chains, to be described, put the tubes of said frames into the warps to thereby putinto position the tuft-yarns carried thereby. The lever h5, mounted on a rock-shaft 7220, said rock-shaft having arms 409, connected by a link h2 with the lay cl2, having dents r, said lay being pivoted at r, are and may be all' substantially as represented in said patents.

The shaft B2 and harness-frames Z912 Z113 b11are substantially the same as represented by like letters in United Sta-tes Patent No. 245,259, dated August 2, 1881; but herein they are actuated in the production of a fabric such as shown in said patent by means which I will now describe. Each frame has connected with it a like rod 2, jointed to one of a series of levers 3 4 5, pivoted at 6 in a stand 7, sustained by the loom-frame A, each lever having a suitable roller-stud, (shown by dotted lines, Figs. 12, 13, and 14,) the stud of lever 3, connected with frame Z212, entering a cam-groove, the shape of which is shown by dotted lines, Fig. 12, in a cam 512x, the cams 513x and 514x for actuating said frames Z913 Z914 being shaped as indicated by dotted lines in said figures, said cams in their operation acting to form sheds in irregular order.

Before entering into a detailed description of the operative parts 1 will first refer to the fabric in Figs. 10a, 10b, and 10. lThe drawings referred to show the warp-threads w, w', and wz, a binding-weft w, a weft w3, and a tuft-holding weft 204, holding tufts wx. Fig. 10a shows some of the completed fabric, the weft w being considered as the last one laid in the cycle of operation of weaving in Fig. 10a. The warps w and w' are lifted and the pick of weft yw3 is inserted in a shed formed between the warps w and w1 and the warp w2 and then w is lowered, forming a shed in which is inserted the usual tuft-yarn tubes 30, and then the weft 'L04 is inserted in said shed to cross the tuft-yarns and the tubes are raised in usual mannerand at the proper times to bend the tuft-yarns about the weft w1, and thereafter at suitable times the tuft-yarn is cut, leaving tufts or loops 105x about the weft w4, and the two picks w3 and w* are beat at one operation into the fell and the third shed is formed, this time, however, by lowering w next to w' and lifting wg, thus making the third shed, in which is inserted the weft 105.

From the foregoing it will be understood IOO IIO

that the machine to be described forms a plurality of sheds while the lay is maintained on its back stroke, one of said sheds receivinga pick of weft which appears at the back of the fabric and the 'other pick of weft, which is embraced by the tuft-yarns,and said two picks inserted in the sheds and one of them embraced by the tuft-yarns, and the threads having been preferably crossed for the third shed are beat up by the lay to the fell. During the operation of the reed the needle or weft carrier is retracted and kept outside of the shed. Preferably during this beat of the lay the third shed will be completed for the reception of the third weft, which constitutes the binding-weft for the fabric. Herein the movement of the harness mechanism in the formation of the sheds is so timed as to form a longer dwell between the second and third sheds than between the tirst and second sheds, and so also in the operation of the needle or weft carrieror whatever weft-inserting means is employed there is a longer dwell between the second and third picks than between the first and second picks, or, in other words, two` of the three sheds 'completing the cycle of manufacture of the fabric described are made oneimmediately after the other and following quickly the insertion and withdrawal of the needle to be described, while the third shed is made after the lapse of a longer interval of the time of the loom than that between the first and second sheds. The third pickinserted in the third shed is beat up alongside of the two picks previously inserted, it acting as a binding-pick and separating successive picks holding the tutt-yarns and act-ing in holding the said tutt-yarn picks seated on picks under them.

The shaft- B2 in the invention to be herein described and claimed has a cam B, the shape of which is shown in Fig. 3, which acts against a roller B', connected with the arm h5, and imparts to the lay its movements to beat in the weft or picks into the shed, said cam having, as herein represented, two throw-points B3 B4, contained substantially within one hundred and eighty degrees of the cycle of the cam, so that said lay is retained in its backward position by a suitable spring 8 for substantially half of the rotation of said cam, the two throw-points B3 and B4 moving the lay forward twice in succession during substantially one-half the time of the cam in completing one rotation, the throw-point B3 moving the lay forward immediately after the withdrawal of the needle from the second shed in the cycle of operation of the machine in weaving the fabric, the longer space between the th row-points B3 and B4 being utilized to enable a shed to be formed and a third pick or weft-crossing to be inserted into a third shed preparatory to the action of the throwpoint B3 in again moving the lay forward to beat in the third pick. While the part of the cam B between the throw-points Bs and B4 in the rotation of said cam in the direction of the arrow thereon, Fig. 3, is in contact with the roller B' two sheds are formed in the warp, one quickly following the other, the two sheds being open only long enough to enable two movements ofthe filling-carrier, one after the other, to be made effective in inserting two picks of filling byinserting and withdrawing the carrier, the first pick not being beat by the reed of the lay into the fell of the cloth.

The transferring mechanism, comprising the means hereinbefore designated by that term and common to said United States Patents Nos. 446,402 and 490,237, in order that it may be moved to coperate properly with the lay, the shed-forming mechanism, and the weft-carrying mechanism, must have imparted to it one complete forward and backward movement to each rotation of the shaft B2, and to do this said shaft has been provided with a cam H, the shape of which is represented by dotted outline in Fig. 4, it acting on a roller carried by the arm el, Rising-and-falliug movement is given to a part of said transferring mechanism to engage a spool, take it from the chain, put the spool back into the chain, and leave it there by a cam H' of the shape designated by full and dotted lines in Fig. 3, it acting -upon the lever carried by the arm f4, before described. Movement is imparted to the transferring mechanism by these two cams H and H', their shape being such as to cooperate as to the time of their movements with the operation of the weft-inserting mechanism and lay, as herein described.

The shaft B2 is provided with a toothed wheel C, which is engaged by a pinion C' on a power-shaft C2, having a suitable belt-pulley C3, of the friction order, it receiving a belt C4, said pulley cooperating witha mating friction-pulley CXX, fast on said shaft, the rotation of the power-shaft rotating the gear C and the cam-shaft B2 to operate the mechanism for weaving.

The shafts B2 and C2 are embraced in their bearings by antifriction-roller bearings composed of a series of bearing-rollers 20, mon nted loosely in a suitable cage 2l. One of these roller-bearings is represented as detached in Fig. 10.

The wheel C is represented as provided at one face with a cam-ledge C5, the opposite side of which is acted upon by suitable rollers d d', the roller d being mounted upon a lever D', mounted on a stud D2, held in an upright or brace DX, the outer end of said lever having jointed to it a link D3, in turn jointed tothe short arm of a lever D", mounted on a rock-shaft D5, suitably sustained in the auxiliary frame A8, the upper end of said lever having jointed to it alink D, which in turn is jointed to a carriage D7, mounted upon a suitable guide-rod D8, held in a guidingframe D9, supported by brackets D10, bolted to the framework A8 of the machine, said carriage at a point above said guideway having IOO IIO

connected with it, by suitable screws 22, a

needle leaving in the shed a double filling,

the said filling at one edge of the woven fabric being locked by a suitable selVage-thread passed through it. It may be `as provided forin United States Patent No. 490,237, dated January 17, 1893.

The roller d is carried by a lever E, pivoted at E upon an ear E2, extended from the lever D', said lever E being acted upon by a suitable spring E3, the tension of which may be adjusted as desired by or through a setscrew E4 to thereby cause the rollers d and d' to hug closely, but yieldingly, the opposite sides of the cam-rib C5. This cam-rib (represented in Fig. 2) is of peculiar constructionthat is, it has three throw-points c c4 c2 for insert-ing the needle in the shed, the throwpoints c and c' being closer together than either the points c and c2 or c2 and c. The high points c and c are distant one from the other only sufficient toenable the needle moved by the high pointc to be retracted from the shed while a new shed is being made, the throw-point c' immediately actuating the needle again and inserting it into the second of the three sheds necessary, as my invention is herein represented, to be made in one cycle of operation of the loom. The second shed is made while the depressed part X of the cam-rib C5, moving inthe direction of the arrow, Fig. 2, between the points c c', is embraced by the rollers d and d', 'the part c3 of the said cam-rib retracting the needle from the second shed, the distance along the camrib between the throw-points c' and c2 being sufiicient to afford time in which a third shed may be made, and while the needle is held at rest outside the shed to enable the lay to be moved forward and beat toward the fell the two double picks of filling previously inserted in two successive sheds previously formed. After the lay has been moved forward bythe point B3 of the cam B to cause the reed r to beat in the two picks w3 and @U4 of filling, the pick 104 having the tuft-yarns W laid about it, the third shed is opened, so that by the time that the portion c4 of the camledge comes into operative position the needie is again thrust into the shed with its Weft m5, it completing its movement through the shed as the high point c2 cornes between the rollers d d', it being retracted as the part c5 of the cam comes into operative position between the rollers d and d, and between the point c? and the point c, -forming part of the high point c, said third pick of weft I105 is laid and beat into the third shed. 'lhe lay1 is .moved forward to beat in the third pick 105 of filling hy the part of the cam-rib c5e6,it then coming between the rollers d and d, and the harness-frames are then operated to open the shed to again receive the needle, which is thrust through thel shed as the high point c acts. As herein represented,these three picks are repeated in the order stated in the production of one row of tufts, the said three' picks, three sheds, and two beats of the lay completing the cycle of operation of setting a row of tufts.

Prior to this invent-ion it has been customary to beat into the fell each pick immediately after the same has been laid in the shed and very considerable time of the loom is wasted, the filling-carrier standing still during the time that the lay is moved to beat in each filling.

I find that I may produce a fabric of good quality, not at all inferior to that heretofore made on this class of loom, by oniittingone beat of the lay from the cycle of usual operation-that is, I introduce two picks of filling successively in two sheds and beat these two picks up to the fellin one forward movement ofthe lay, such beat forcing the second pick surrounded by the tufts forward to the fell and seating said tufts on the first pick, as represented in said Patent No. 245,259. It will, however, be underst-ood that my invention is applicable in weaving any tufted fabric, whether the cycle for each row of tufts is completed by the insertion of three picks or more, so long as I so construct the needleoperating cam that it may insert ltwo picks of filling in two successive sheds followed by one beat of the lay and also whether the sheds are formed by a dierent movement of the harnesses, as herein described, and also withany other well-known transferring motion to place the tuft-yarns in the shed, taking them from the chain-carriers and returning them again, as is common to this class of looms.

I will now`describe the spool-frames, their carrying-chains, and actuating devices, referring to Figs. 3, 4, 5, 8, and 9.

The spool-frame is composed of a bar 24, having at its ends suitable arms to be inserted in the spaces of the links of the chains, to be described, each frame having at each end a suitable hook or engaging device 26 to engage the chain and retain the spool-frame in position thereon.

'lhe spool-frame has suitable intermediate bearings "27 and suitable end bearings 28, said bearings sustaining a plurality of spools 29 end to end, the number of spools used in each beam (they containing the tuft-yarns) and the length of the beam depending upon the width of the tufted fabric to be woven.

In order to arrest the beam 24 to maintain a substantially straight-line position or to prevent it from sagging, so that each spoolframe when taken from its chain to put its tubes 30, containing the tutt-yarns, between adjacent warpmhreads and present the tuft- IOO IOS

IIO

yarns in position With relation to the warpthreads to be held locked or crossed by a pick of filling, as common in looms for weaving tufted fabric or as in said Patent No. 490,237, and enable the ends of the tuft-yarns to stand in a plane substantially parallel with the plane of the shed, I have provided the beam 2t, constituting the body of the spool-frame, with a metallic T-shaped brace 31, of a shape in cross-section to leave arms 32 33, as represented in Fig. 9, said brace being firmly secured in any suitable way, as by screws 34, to the under side of the beam, the portion 32 overlapping one side of the beam and the portion 33 extending downwardly in substantial aliuemeut with the portion 32 and constituting a stilfening means for the beam to prevent sagging thereof between its ends due to the weight of the spools and the attached tubes. The portions 32 and 33 of the brace also have seated upon them and suitably secured thereto, as by solder, the upper rear side of the tubes 30. The tuft-yarn beam will be handled by the transferring device and the tuft-yarns will be inserted in the warp, as provided for in said Patent No. 490,237, to make the fabric described in No. 245,259.

The spool-frames, of any desired number, according to the pattern to be woven, are carried by chains 35, composed of double and single links jointed together, there being a plurality of such chains to thereby support the opposite ends of the spool-frame, the arms 25, as stated, entering spaces between the walls of the double links of the chain, said spool-frames being brought in position to be taken in succession in any predetermined order from the chain by the transferring means for the formation of the rows of tufts in the tufted fabric, and after the tuft-yarns of the spool-frame have been inserted and bound in usual manner in the warp the said tuft-yarns are cut off and the spool-frames'are returned again to the chains.

During the time that the transferring mechanism operates to take a spool-frame from the chain and return it to the chain the chains remain at rest, to thereby insure the reengagement of the spool-frames with the chains and the return of the spool-frames to the particular point in the chains from which they were taken.

A pawl-and-ratchet mechanism have heretofore been used to actuate the carrier-chain step by step in order to put each spool-frame in proper position to be engaged by the transferrerniechanism; but in the use of such means where the chain is long and carries a number of frames the resistance to starting the chain is so great that sometimes the shaft having the ratchet which is engaged by the pawl to move the chain will fail to turn to the right position, and consequently the chains and the spool-frames will not register properly to be engaged by the transferring mechanism, and consequently the transferring mechanism will fail to take a frame from the chain. To insure the easy and accurate movementof a part of the chains from which the spool-frame is to be taken, I have provided a secondary chain moving or starting means acting intermittingly and independently of the main actuating means for intermittingly moving the chains carrying the spool-frames, said secondary means moving a registering-shaft, which insures the starting of that part of the carrying-chains from Which the spool-frame is to be taken by the tranferring mechanism, and that this registering-shaft may be moved to start the chain easily and without shock and be moved for the required distance I have so constructed the main actuating means for moving the main weight of the chain that said means always maintains a certain amount of slack in the carrying-chain near the registering-shaft, so that when the secondary means for starting the said shaft to move the chain is started into action said secondary means has only to overcome practicallya small portion of the weight of the chain, and as soon as the registering-shaft gets under way the main actuating means for the chain comes into play and the two actuating means work in unison to complete the movement of the chains, leaving, however, slack in the chain near the registering-shaft to enable the said shaft to be again started without first moving or starting up the entire weight of the chain. The main actuating means may move the main weight of the chain at the same time that the registering-shaft starts the chain, maintaining the same amount of slack in the chains between said main actuating means and the registering-shaft, or, if desired, the main actuating means may commence its movement earlier and terminate its movement later than the registering-shaft, there being enough slack in the chain provided for that purpose, this being effected bychanging the relative diameters of the wheels 63 and 65. This chain is frequently provided with many hundred spools, and the power required to move it is very considerable. The chains, twoin number, as herein represented, carry usually in each double link a spoolframe F, (represented in Fig. 4 by a straight dotted liue,) several of said spool-frames being represented by full lines in Fig. 3, I having chosen to designate by said letter the spools, tubes, duc. The chains 35 are endless and are extended over the sprocket-wheels 36, carried by a registering-shaft 37, and the opposite end of the chain (see Fig. 4) is extended above, as herein represented, snitable sprocket-wheels 38 on a suitable crossshaft 39,sustained in suitable hangers 40, secured by bolts 41 to a suitable cross-beam 42, attached, as maybe, to the ceiling. Between these sprocket-wheels 36 and 38 the chain is engaged bysprocket-wheels 43 and 44 and by other sprocket-wheels 56 and 57. The upper and lower runs of the chain pass, respectively,

668,597 L' jf over sprocket-wheels 43 and 44, carried, respectively, by shafts 45 and 46, sustained, respectively, in suitable stands 47 and 48. Between the stands 40 and 48 there are other stands 49, having suitable bearings for shafts 52 and 53 extended across the loom-frame and in practice supported in like manner at or near its opposite ends. The shafts 52 and 53 are provided, respectively, with toothed gears 54 and 55, meshing one with the other, and each shaft 52 and 53 has located upon it in line with the sprocket-wheels 43 and 38 of the shafts 45 and 39 suitable sprocket-wheels 56 57 to receive the upper and lower runs of the chain, said sprocket-wheels being shown in the detail Fig. 15, it being a section looking to the left from the dotted line x4, Fig. 4.

The upper and lower runs of the chain are kept seated upon the sprocket-wheels 56 and 57, constituting the main driving means for the chain 35, by or throughsuit-able pressers (represented as sheaves 58) bearing upon the upper side of the chain, said sheaves being sustained by brackets of any usual or suitable form, preferably from the ceiling. The chain is applied to the sprocket-wheels so as to leave a definite amount of slack chain between the sprocketwheels carried on the shafts 52 and 53 and the sprocket-wheels 43 and 44, the distance between these wheels being so proportioned that the weight of the chains and spool-frames keep the chains taut between the wheels 43 and 44 and the sprocketwheel 36 on the registering-shaft.

The chain registering or starting shaft 37, having its bearings in the framework A of the loom, is provided, as herein represented, outside said framework with a sprocket-wheel 60, over which is extended the chain 61, which constitutes one form of secondary actuating means operating to start the registry-shaft and the spool-carrying chain positively, being extended over a sprocket-wheel 62, in line with it and partially indicated by breaking away a notched wheel 63, mounted on the same shaft-64, it being a short shaft sustained in the framework A. The shaft 53, at one end thereof outside the bracket 49, has applied to it a notched wheel 65.

The main shaft B2, which is rotated continuously, has applied to it a bevel-pinion 66, which engages two bevel-gears 67 and 68, mounted loosely on a shaft 69, (also represented as rotated continuously,) each bevelgear 67 and 68 being kept normally in engagement with the bevel-gear 66 by suitable collars 70 and 7], suitably fixed to the framework A, the pressure of engagement' of the said gears heilig controlled by the abutting of the gears 67 and 68 against collars 72 and 73, attached to the shaft 69. The shaft 69, between the collars 72 and 73, has a groove which is entered by a spline of a sleeve 74, having an annular groove and surrounded by the forked end of a lever 75, pivoted at 76 and having a suitable handle 77, by which said sleeve may be moved longitudinally of the shaft69. Theendsofthissleevehavesuitable teeth or projections to coperate with suitable notches at the inner ends of the gears 67 and 68, and when the said sleeve engages one or the other of the gears 67 or 68 the shaft 69 is rotated in one or the other direction, and by changing the position of the sleeve 74 by the lever 75 this direction of rotation of the shaft 69 may be changed at will, or by putting the sleeve in a central position 'wherein its opposite ends are disengaged from both pinions 67 and 68 the shaft B2 may be run and actuate the gears 67 and 68, leaving the shaft 69 at rest. Assuming that the operative position ot' the gear 66 is in engagement with the gear 72 and that the sleeve 74 engages the gear 67,'then through suitable means to be described for imparting an intermitting motion from a rotary motion the shaft 53 and 64 will be rotated intermittingly in a direction, let it be supposed, to feed the chain in the direction of the arrow thereon, Fig. 4; bntif for any reason it becomes necessary to run the chain backwardly, as is often the case, then the clutch 74 will be moved to engage the gear 68, such backward movement being used at times to repeat the pattern or to use in areverse order the spool-frames. Sometimes, however, it is necessary to turn the chains and move the spool-frame while the loom is at rest, and to do this I have provided a neutral or central position for the sleeve 74. That the main and secondary chain-actuating means may be moved intermittinglyfrom the continuously-rotating shaft, as 69, said shaft is shown as having at its upper end a bevelgear 79,having two series of teeth, one at its upper side and the other at the lower side thereof, the teeth at the upper side engaging the `teeth of the bevel-gear 80, fast on a rock-shaft 8l, sustained in suitable bearings formed 'for it and connected with some part of the loom-frame or one of the stands referred to. The opposite end of the shaft 81 has a bevel-gear 82, which engages a bevel-gear 83 on a short shaft 84, provided with a hub 85, having a pin 86, said pin engaging intermittingly the notches 87 of the wheel 65 and moving said wheel and the shaft 53 step by step, the rotation of the shaft 53 being prevented when the pinA 86 passes from a notch 87 in the rotation of the shaft 84 by or through the concavities 88 of said .wheel or plate 65 engaging the circular periphery of the hub 85, said notched plate and projection constituting one form of device for imparting an intermitting lnovementfrom a continuons rotating movement, said device being commonly designated as a pin-andstart wheel; but instead of such form of device I may use any other usual and suitable device capable of imparting intermitting movement from a continuous rotating movement. The teeth at the under side of the gear 79 mesh with and rotate a pinion 89 on ashort shaft. 90, suitably supported in the framework A and having connected with it a hub 91, provided with a pin or projection 92, which enters one after the other a series of notches 93 in a notched plate 94, fast on the shaft (i4, said projection 92 and plate 94 constituting a means such as described for imparting intermitting movement to the shaft L54 and the chain 6l from a contin uously-moving shaft.

It will be obvious from the foregoing description that the shaft 53, rotated intermittingly, will, through the gears 55 and 54, rotate intermittingly the sprocket-wheels 56 and 57, constituting the main driving mechanism for the chain 35, and a certain amount or" slack having been provided forin the chain and located to appear at all times between said sprocket wheels 56 and 57 and the sprocket-wheels 43 and 44 it will be obvious that said slack will always be maintained in the chain, but that it may be partially taken up whenever the starting registering or starting shaft37 is putin motion, as it. will be by the auxiliary chain GI, immediately after a spool-frame has been put back again into the chain 35, for it is at that time that said chain must be started to put another or succeeding spool-frame in position to be taken therefrom by the transferring means.

In the operation of the loom let it be supposed that the chain 35 and the startingchain 6l were at rest while the transferring mea-ns was taking a spool-frame from the chain to utilize the tuft-yarns of the spool in the production of a row of tufts and until said spool-frame had been returned to the chain. A spool having been returned, it will be supposed that the projection 92 enters a notch in the plate 64 and imparts motion to the chain Gl, it in engagement with the sprocket-wheel GO putting the registering or starting shaft 37 in motion to thus start it and the chain 35 to bring another spool-frame into working position. To start the registering-shaft, the auxiliary chain Gl has to exert but little strain, because of the slack in the chain 35; but when the said shaft has been started, as it may be by a suitable mechanism to impart to it the intermitting movement from a continuously-moving shaft, one form of which mechanism is herein shown, then the rotation of the shaft 52 and 53 is started and, acting through the sprocketwheels 56 and 57, moves the chain 35, thus supplementing the action of the registeringshaft (il. The shafts 52 and 53 stop, preferably, after the registering-shaft 37 has come to rest, its chain 61 having been stopped, the chain being moved far enough to maintain the usual amount of slack, as stated, so that when the shaft 37 is to be again started after the return to the chain 35 of a spool-frame the auxiliary chain (il may start the main chain easily. To provide for running the chain 35 in either direction when the loom is at rest, I have extended the shaft 84, which in Fig. 4 is represented in section taken in the line 006, Fig. 5, and I have provided said shaft outside a suitable stand 94X, suspending, as herein represented, from the ceiling,

with a fast pulley 95 and each side of the same a loose pulley, as 9G 97, one of which is driven by an open belt and the other by a cross-belt deriving motion from any countershaft, the shaft 84 and the shafts 52 and being driven in one or the other direction, according to which one of said belts is put upon the fast pulley 95. As stated, the chain 35, with its spool-frames, is very heavy, that depending upon the length of the same, and frequently this chain and its load amounts to many hundreds of pounds, and to reduce the power required to move this chain I pro vide all the shafts carrying the chains with roller-bearings, some of said roller-bearings being substantially the same as the rollerbearings sustaining` the shaft B2 and C2, one form of suitable roller-bearing for this purpose being represented enlarged in the detail Fig. l0; but this` invention is not limited to the particular form shown of roller-bearing. To retain the slack in the chain 35 between the sprocket-wheels 54 and 55 and 43 and 44 and to insure uniformity in movement. of the chain 35,1 provide the shafts 45 and 46, respectively, with toothed gears 45 and 46X, which mesh one with the other, so that the part of the chain bet wecn the wheels 43 and 44 and the wheels 3G on the registeringshaft will always remain at the same tension, said wheels 43 and 44 deriving their movement only through the chain actuated bythe main and secondary chain-actuating mea-ns.

This invention is not limited to the exact location of the continuously-rotating shaft instrumental in driving the chains nor to the precise form of intermediate connection shown between the said continuously-rotating shaft and the intermittingly-rotating shafts which move the chains intermittingly, as described.

For economy and lightness I prefer to form the T-shaped brace in two parts or of two tinned angle-irons soldered or riveted together at one of the angles, I thereby forming a very stiff brace combined with the maximum of lightness. This T-shaped brace when combined with the usual wood-supporting bar forms a deep rib projecting from the barand acts to stiften the bar, which` together with the rib attached tothe bar itself, stiffens the bar both laterally and vertically.

A spool-frame constructed as herein described is adapted to be used in any wellknown tutt-fabric loom using spool-frames with great advantage.

When the adjusting or starting shaft 37 is moved, as has been described, to bring another spool-frame into working position, the quick rotary starting movement of the shaft and also the stopping of the movement of the shaft acts to swing that spool-frame which is in its most downward position and is the next to be taken from the chain by the transferrer.

As the spool-frames are now commonly held they may swing back and forth and get out of place, and consequently the transfer- IOC IIC

rer When it is moved to take a frame from the chain is liable at limes to m-iss and not engage the spool-frame out of its proper posi- In order to overcome this difficulty, I have devised a spool-frame positioning and locking device X, herein illustrated as a notched disk, adapted in its rotation to engage the journals 26X, sustaining the spools 29 in the spool-frame.

The guiding-wheel is shown as fastened to and rotating with the sprocket-wheel of the starting-shaft 37, and the notches 81X in the periphery thereof embrace the journals 26X of the spools as the disk is rotated and hold the frame from swinging. In the downward movement of the spool-frames, after the starting-shaft is moved and just before the pin of the spool comes into position to be engaged by the guide-wheel 80X, I provide a spoolframe-detaining device consisting of a flat spring 82X, carried by a suitable arm 83X, attached to the loom-frame, said device contacting with the outer end of the spool-frame outside of the tuft-yarn tubes. This spring acts to hold back the spool-frame while the guide-wheel is advancing, aiding the journal 26X of the spool to enter the notches 81 of the guide-wheel. There is an arm 83X and spring 82X at each side of the loom-frame.
